High Accuracy Satellite Receiving Controller and Associated Method

A high accuracy satellite receiving controller, comprising:

• an analog-to-digital converter (ADC), for receiving an analog temperature and converting the same into a digital temperature;
• a global positioning system (GPS) receiving module, for performing satellite positioning;
• a frequency synthesizer, coupled to an external non-temperature-compensated crystal oscillator (non-TCXO), for generating an oscillating frequency signal for operating the GPS receiving module;
• and
• a control unit, coupled to the ADC and the GPS receiving module;
• wherein, the control unit generates an oscillation frequency adjustment value to the GPS receiving module to compensate accuracy of satellite positioning, and adaptively updates a temperature/frequency offset data.
